8 Claims. (01.36-17) Y My invention relates, generally, to shoes forwidth of the insole within the bounds of; the men, ladies and childrenand particularly to an stitched inseam 6- securing the insole and weltimproved construction for Goodyear welt shoes. to the upper and withinthe bounds of the turned The object of my invention is to provide aperunder lower heel edge portion '7 of the counter forated elasticfiller and a shank and heel stiffener portion of theupper which providesthe usual heel 5 which are adapted to be interposed between the seat 8for the shoe. A

insole and outsole of Goodyear welt shoes with In carrying out theparticular aim-of my inthe filler disposed wholly within the inseam andvention, I cement or similarly secure a resilient heel seat cavity ofthe shoe to set up a combined rubber fi le B having the Shank Portion 9a a 10 elastic and pneumatic cushion effect for the enh P t 10 t0 thelowe ace of the insole 3 10 tire foot of the wearer of the shoe, and,which ineluding'the S a and heel Portions 9 a d 10 1 structure willpermit the shoe to be assembled and the o and the fi e A is adapted t pymanufactured upon a, production b i i h only space within the bounds ofthe aforesaid factories without the necessity of employing inseam andheel seat cavity between the insole 3 special machinery otnow used inthe manufacand outsole 1 0f the s 15 ture of the present'day styles ofshoes.

After the outsole has been applied to the shoe, a plurality of.heel lifts 19 are secured in position upon the outer face of the heelportion of the outsole by means of nails 20 and then a rubber or othersuitable heel 21 is applied to the lifts 19 by. means of nails 22 whichpass into' the heel seat of the shoe by passing around the edge of heelplate section 12 of the shank and heelstiifener 11.

Due to thefact that the shank and heel stiffener of 'my improved shoestructure extends to.

the heel portion of the shoe, and, further due to the fact that the heelsection 12 'of the shank and heel stiffener is longitudinally andtransversely concaved-convexed and provided with a central aperture 13of such shape as to receive the plug or lug extension 14 of the heelportion 10 of the resilient rubber filler A, it will be observed that Iprovidea shoe structure which will provide an elastic and pneumaticcushion sole 'for the shoe and give an elastic and pneumatic cushioneffect to the ball, the arch and to the heel of the foot of the wearerof the shoe with.

plug extension 14 between the heel end 12 of the'shank and heelstiffener 11 and the heel portion 10 of therubber elastic filler A.

In order to lighten the rubber elastic filler and to afford apneumaticeffect to the sole of the shoe, as well as an elastic, orresilient effect, I provide the-filler A with a multiplicity ofvertically disposed punched openings 24, including.

the shank and heel sections 9 and 10 thereof, and I further provide theplug extension 14 of the heel section 10 of the filler with a pluralityof suitable punched vertical openings 25 to provide a multiplicity ofair pockets for the rubber elastic filler between the insole and outsolethroughout the entire area thereof, as well as the air pocket 23surrounding the 'plug extension 14 of the. heel portion of the elasticfiller.-

By insertingthe lower end of the rubber elas- .tic plug 14 of the heelportion 10 of the filler A, in the opening of the dished heel portion ofthe arch shank, it prevents shifting displacement of the lower end ofthe ,plug extension relative to the heel portion .of the shank and heelstiffener and the air space surrounding the plug extension between theheel portion of the flller' and the heel portion of the shank and heelstiffener permits the heel portion 10 of the filler to yield downwardlyand the plug extension to expand radially in yieldingunder pressure toaccommodate the shape of the bottom of the heel of the wearer of theshoe and to afford a greater amount of elastic and pneumatic cushioneffect to the heel of the foot thanto the arch and ball positionsthereof, yet aflording a substantial centralized elastic and pneumaticcushion effect to the heel to prevent any uneasiness to .the wearer ofthe shoe by properly shaping itself to support the-heel of the wearer ofthe shoe to make walking and standing non-tiresome to the foot.

Therubber filler of my present invention, it

will be apparent from-the illustration, is of unlform thicknessthroughoutits entire area ex-; cepting at the plug extension thereof,thus before being applied to the shoe, its upper and lower planes areparallel arranged. The lower face of the plugiis also preferably fiatand parallel to the upper and lower planes of the filler proper. Thelower face of .the plug extension being flat establishes a slight airspace 26 between the lower face of the plug extension and the concavedupper'face of the heel portion of the outsole when the lower end of theplug extension is received in the aperture of the dished heel plateportion of the arch shank. This lower air space 26 also aids with theair space 23 around the plug extension in allowing the plug extension tobe compressed by heel pressure to cause the upper plane thereof toreadily shape itself to the shape of the bottom of the heel of thewearer of the shoe. The. same effect is provided when the heel portionof the shank and heel stiffener is not-provided with a central apertureto receive the plug extension, as is manifest.

A shoe of the character disclosed, must of necessity be made in quantityproduction, hence the simple and practical manner of assembling has beenworked out only through extensiveerperiments and, as shown, the shoe isconsidered by shoe experts a far reaching improvement over my formerPatent Number 1,476,690, which can be made by a cobbler all right,.butnot under any circumstances can it be made in quantity production, asmodern shoe machinery cannot be utilized in the manufacture of the shoeconstructed as disclosed and illustrated in my former patent.

The many advantages of the herein described invention will readilysuggest themselves to those skilled in the art to which it appertains.

From the foregoing description, it is evident that a simple device forthis purpose has been disclosed, but it is to be understood that I donot desire to restrict, or limit myself to the very de tails of theconstruction shown and described, which is merely illustrative, it beingobvious that changes, not involving the exercise of invention, may bemade without conflicting or departing from the spirit of the inventionwithin the scope of the appended claims.

What I claim is:
